derived from old mystical woodsmen tellings, that explained unexplainable penis disappearances, of a creature conceived when a chicken mates with a gobblin that has an unhealthy appetite for penises. And this creature would sneak into their dwellings after dusk and harvest their penises for a very bland consumption. But in all reality it was just the woodsmen sleepwalking and chopping off each others penises.

Son: "Dad!!! My penis has mysteriously disappeared!!!! What could have caused this to happen?"
Woodsmen: "Son. It must have been a cock gobblin."
